wow....today we have learned to program the lift....
never noe that the lift we used everyday is quite easy programed....
(today we used java to program)
and....add on another thing...
we also use the RFID card (which oledy been programed??)!!!
after we tap the card, it automatically bring us to the level which is written inside the RFID card.
It means that....RFID technology can be implemented in as access control system!!!
mayb all the resident in a condo, will be given one RFID card,
they must tap the card to operate the lift,
thus, they can only go to the level where they stay....
this can prevent outsider from disturbing the residents...
so cool!!!....
not sure whether this has been implemented at any places?
